Both E2510 and E2508 are for synthesized speech devices. The difference lies in complexity: - E2508 requires message formulation by spelling and access by physical contact only. - E2510 permits multiple methods of message formulation (letters, pictures, symbols, etc.) and multiple methods of device access (touch, eye-tracking, switches, etc.). E2510 is typically for individuals with more complex physical needs that prevent them from using simpler access methods.

Frequently asked questions

Yes, accessories (e.g., mounting systems, specialized access devices) are covered if they are determined to be medically necessary for the patient to use the SGD and the medical necessity is clearly documented in the SLP's formal evaluation. They are usually billed with separate codes (e.g., E2512, E2599) and require specific information on the claim (manufacturer name, product name, and number).
